    Mitigation Practices for Frequent Accidents in High Rise Building Construction
    (SLIIT, 2022-02-11) Delpachitra, Y; Allis, C
    High-rise building construction accidents are observed within the construction industry in Sri Lanka. These accidents represent a significant loss for the construction industry in terms of lives, cost, time, and the reputation of the construction company. To overcome those losses, this research aimed to develop the framework as guidance to mitigate frequently happening accidents in high-rise building construction in Sri Lanka. It was achieved by three main objectives, identify the frequent accidents in high-rise building construction, investigate the causes of frequent accidents happen and analyze the strategies to minimize them. The first two objectives were completed by literature review, and the third objective was completed by data collection while developing the second objective. The data collection was done through semi-structured interviews with 12 professionals who work as health and safety officers, project managers, engineers, and quantity surveyors in high-rise building construction. Only those who work in the Colombo area were considered here as a limitation. Under the first objective, scaffolding accidents, struck by falling objects, plant, and machinery accidents, falling from a height, and fire accidents were identified as frequent accidents in high rise building construction, and causes were listed below the human factors, material, and equipment factors, environmental Factors, safety technology factors, and management failures as the second objective. Essentially risk assessment, developing the site conditions, conducting training programs establishing safety system with the procedure control system, and establishing penalty procedure were the discoveries of the third objective, and those are categorized separately in the pre-construction stage and post-construction stage. According to all these findings, the framework was developed to identified relevant mitigation practices for the causes of high-rise building construction accidents, and this research recommended for government to introduce new regulations for safety while strictly following up the safety system of the high-rise building construction sites to reduce the accidents.

    DELAYS AND DISRUPTIONS IN THE CONSTRUCTION INDUSTRY DURING THE GLOBAL PANDEMIC
    (researchgate.net, 2022-06-24) Gammanage, S. H; Gunarathna, N
    COVID-19 pandemic has become a global catastrophe today dragging many nations towards severe economic distress. The Sri Lankan economy has no exception. Not surprisingly, the sluggish economic conditions in the country have adversely affected the construction industry in Sri Lanka. The pandemic has resulted in almost every construction project getting delayed or disrupted. This research aims to determine the factors that caused delays and disruptions in large scale construction projects in Sri Lanka due to pandemic. The overall impact of the global pandemic on construction projects in both local and international platforms were identified through a comprehensive literature review. Additionally, the impact on the local domain in terms of delay and disruption was assessed based on exploratory interviews and survey questionnaire disseminated among industry experts. Final conclusions were drawn by conducting 9 case studies and analysing responses to survey questionnaire provided by 30 industry practitioners. This study assisted in finding measures and mechanisms currently in use to mitigate the impact of delay and disruption of the construction phase of construction projects. The findings also paved the way to recognize innovative mitigation strategies to control the adverse impact on on-going construction projects. Analysis of the responses concluded that, delay in project kick-off, delays in material delivery, shortage of material, project suspension, reduction in the workforce productivity, health and safety concerns, regular price escalations as the key elements attributed to impact the project progress. The study has identified the present mitigating controls over delays or disruption are barely sufficient to address the concern and thus emphasised the need to resort to more effective techniques to remedy the issue.
